From the front of the pulley to the back of the rad support would be great. Then I will know for sure, not sure if it is the same as a duster. JDMopar got me a measurement from his Duster not sure if they are the same.
Trevor, I can get ya close... I have my radiator in, but could go to bottom/back of that support... Do you want to the front of the pulley, or into the depth where the bolt is?
